The ALTA Wireless Resistance Sensor reads the resistance across any resistive load and reports back the measured resistance. The resistance sensor leads are meant to connect to passive devices only, connecting the sensor leads to any voltage or power source that may damage the sensor. It is programmed to sleep for a user-given time interval (heartbeat) and then wake up, convert the analog data, mathematically compute the resistance, and transmit the data to the gateway, where it is then logged into the cloud service. The user can configure defined thresholds and have the system alert on threshold breaches.
